Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of automotive parts processing equipment, specifically relating to a casting mold for producing automotive parts impellers. Background Technology
[0002] The casting mold for automotive component impellers is a key tooling device used in impeller manufacturing, primarily for the forming and cooling of molten metal. These molds are typically made of high-strength alloy materials to ensure stability and durability under high-temperature, high-pressure casting conditions. Their structural design must strictly adhere to the impeller's geometry and hydrodynamic requirements to guarantee the precision and performance of the final product. The mold usually includes core components such as a cavity, gating system, cooling system, and ejection mechanism to achieve the filling, solidification, and demolding of molten metal.
[0003] In the current production process of automotive impeller casting molds, insufficient filling caused by venting channel blockage is a typical problem. Because traditional molds often have straight, narrow venting channels, during high-speed casting, oxide scale or tiny impurities carried by the molten metal easily accumulate within these channels, obstructing the gas discharge path. This prevents timely gas discharge from the cavity's end, causing gas compression at the molten metal flow front and ultimately resulting in insufficient filling. Specifically, this manifests as irregular missing material or incomplete outlines at the blade tips, severely impacting the impeller's fluid performance and service life. Utility Model Content
[0004] The purpose of this utility model is to provide a casting mold for the production of automotive parts impellers, aiming to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A casting mold for producing automotive component impellers, comprising, The load-bearing mechanism includes a bracket, a support base fixedly installed on the top of the bracket, and a casting assembly disposed on the top of the support base; The anti-clogging mechanism includes an inner ring fixedly installed on the top of the support base, an exhaust assembly disposed inside the inner ring, a connecting hole opened on the outside of the inner ring, and a guide slope opened at the edge of the connecting hole. And a cleaning mechanism used in conjunction with the anti-clogging mechanism.
[0006] As a preferred embodiment of the present invention, the exhaust assembly includes an exhaust hole formed on the inner wall of the inner ring, a flared opening formed at one end of the exhaust hole, a narrow slit formed at the other end of the exhaust hole, and an exhaust groove formed in a ring around the inner wall of the exhaust hole.
[0007] As a preferred embodiment of the present invention, the casting assembly includes a mold body fixedly installed in the center of the inner cavity of the support base, and a cavity end disposed on the top of the mold body.
[0008] As a preferred embodiment of the present invention, the casting assembly further includes a casting chamber disposed on the top of the mold body, and a sealing ring fixedly installed in the center of the mold body.
[0009] As a preferred embodiment of this utility model, the cleaning mechanism includes a limiting plate movably mounted on the top of the inner ring, an arc-shaped plate fixedly mounted on the bottom of the limiting plate and located on the inner wall of the inner ring, and a scraper fixedly mounted on the bottom of the arc-shaped plate.
[0010] As a preferred embodiment of the present invention, the cleaning mechanism further includes a scraper fixedly installed on the outside of the scraper, and a grip rod fixedly installed on the top of the limiting plate and located on the outside of the inner ring for hand use.
[0011] As a preferred embodiment of the present invention, the bearing mechanism further includes a connecting ventilation pipe fixedly installed on the outside of the support base, a positioning frame fixedly installed on the bottom of the support base, and an ejector motor fixedly installed on the bottom of the positioning frame.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the gradual channel formed by the exhaust hole, flared mouth and narrow slit in the anti-clogging mechanism effectively intercepts impurities carried by the molten metal while ensuring smooth gas discharge, thus preventing channel blockage at the source. The flared mouth structure significantly reduces the gas flow rate, preventing impurities from entering the exhaust system with the airflow. The annularly distributed exhaust grooves improve exhaust efficiency through multi-directional exhaust, ensuring timely gas discharge from the end of the cavity. Combined with the convenient maintenance function of the cleaning mechanism, any trace impurities that may remain can be thoroughly removed periodically, keeping the exhaust system unobstructed for a long time. This solves the defect of easy clogging of traditional straight exhaust grooves, effectively avoids quality problems such as insufficient material at the blade tip, and improves the integrity and performance reliability of the impeller product.

Detailed Implementation
[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example
[0018] Reference Figures 1-5 This is an embodiment of the present invention, which provides a casting mold for producing automotive component impellers, comprising: The support mechanism 100 includes a bracket 110, a support base 120 fixedly installed on the top of the bracket 110, and a casting assembly 130 disposed on the top of the support base 120. The anti-clogging mechanism 200 includes an inner ring 210 fixedly installed on the top of the support base 120, an exhaust assembly 220 disposed inside the inner ring 210, a connecting hole 230 opened on the outside of the inner ring 210, and a guide slope 240 opened at the edge of the connecting hole 230. And a cleaning mechanism 300 used in conjunction with the anti-clogging mechanism 200.
[0019] The supporting mechanism 100 provides a stable support frame for the entire mold. The cooperation between the bracket 110 and the support base 120 ensures the precise positioning of the casting component 130 and prevents vibration and displacement during the production process. The coordinated design of the inner ring 210 of the anti-blocking mechanism 200 and the venting component 220 can effectively solve the defect problem caused by poor venting during the casting process of traditional molds. The configuration of the cleaning mechanism 300 makes daily maintenance more convenient and improves the service life and production efficiency of the mold.
[0020] Specifically, the exhaust assembly 220 includes an exhaust hole 221 opened on the inner wall of the inner ring 210, a flared opening 222 opened at one end of the exhaust hole 221, a narrow slit opening 223 opened at the other end of the exhaust hole 221, and an exhaust groove 224 opened in a ring around the inner wall of the exhaust hole 221.
[0021] Among them, the exhaust assembly 220, through the specially designed exhaust hole 221 structure, together with the flared mouth 222 and narrow slit mouth 223, forms a gradual exhaust channel, which greatly improves the gas discharge efficiency. The annularly distributed exhaust grooves 224 further enhance the exhaust uniformity, ensure the smooth flow of molten metal in the cavity, and avoid casting defects caused by gas retention. At the same time, this structural design can effectively prevent channel blockage caused by impurity accumulation.
[0022] Furthermore, the casting assembly 130 includes a mold body 131 fixedly installed in the center of the inner cavity of the support base 120, and a cavity end 132 disposed on the top of the mold body 131. The casting assembly 130 also includes a casting chamber 133 disposed on the top of the mold body 131, and a sealing ring 134 fixedly installed in the center of the mold body 131.
[0023] The integrated design of the mold body 131 and the cavity end 132 ensures the dimensional accuracy of the impeller forming. Its precise cavity structure can accurately replicate the complex geometry of the impeller. The central positioning installation method of the inner cavity of the support seat 120 ensures the stability of the mold during high-pressure casting and effectively prevents deformation caused by uneven stress. The optimized design of the casting chamber 133 realizes efficient filling of molten metal. Its streamlined structure helps to reduce turbulence. The setting of the sealing ring 134 not only enhances the sealing performance of the mold and prevents molten metal leakage, but also provides a precise guiding reference for the operation of the cleaning mechanism 300, ensuring the accuracy and safety of the cleaning operation.
[0024] Preferably, the cleaning mechanism 300 includes a limiting plate 310 movably mounted on the top of the inner ring 210, an arc-shaped plate 320 fixedly mounted on the bottom of the limiting plate 310 and located on the inner wall of the inner ring 210, and a scraper 330 fixedly mounted on the bottom of the arc-shaped plate 320. The cleaning mechanism 300 also includes a scraper strip 340 fixedly mounted on the outside of the scraper 330, and a handle 350 fixedly mounted on the top of the limiting plate 310 and located on the outside of the inner ring 210 for hand use.
[0025] Among them, the cleaning mechanism 300 achieves precise positioning through the cooperation of the limiting plate 310 and the inner ring 210. The tight fit between the arc plate 320 and the inner wall ensures that there are no dead corners in the cleaning. The special design of the scraper 330 can effectively remove the impurities accumulated in the exhaust assembly 220. Its operation will not damage the precision exhaust structure, which greatly reduces the difficulty and time cost of maintenance. The addition of the scraper 340 further improves the cleaning effect. Its elastic material can adapt to the complex contour of the exhaust groove 224. The humanized design of the handle 350 allows the operator to easily control the cleaning force and trajectory, which greatly improves the safety and convenience of maintenance operations, while avoiding mold damage caused by improper operation.
[0026] Furthermore, the support mechanism 100 also includes a ventilation pipe 140 fixedly installed on the outside of the support base 120, a positioning frame 150 fixedly installed on the bottom of the support base 120, and an ejector motor 160 fixedly installed on the bottom of the positioning frame 150.
[0027] The ventilation duct 140 enables effective connection between the mold and the external system, ensuring the normal operation of auxiliary functions during production. The positioning frame 150 provides a stable mounting platform for the ejector motor 160. Its precise positioning design ensures the stability and reliability of the ejector mechanism, making the demolding process smoother and more efficient.
[0028] During use, during casting, molten metal is injected from the casting chamber 133 into the cavity of the mold body 131. At this time, the inner ring 210 of the anti-blocking mechanism 200 and the venting assembly 220 work together to collect gas through the flared mouth 222 and discharge it in stages through the narrow slit 223 and the venting groove 224, effectively preventing gas from accumulating. After casting is completed, the ejector motor 160 pushes the casting to be demolded through the positioning frame 150. During the maintenance stage, the operator controls the cleaning mechanism 300 through the lever 350, so that the scraper 330 and the scraper 340 move along the inner wall of the inner ring 210.
[0029] In summary, the stable support frame constructed by the bearing mechanism 100 ensures the precise positioning and operational stability of each component during the casting process. The anti-clogging mechanism 200 adopts a multi-stage venting design, including specially constructed vent holes 221, bell mouths 222, and annular vent grooves 224, which can effectively prevent gas stagnation and impurity blockage, significantly improving venting efficiency and casting quality. The designed cleaning mechanism 300 enables convenient maintenance of the venting system, and its precise scraping structure can thoroughly remove residual impurities without damaging the mold. At the same time, the entire mold system ensures the dimensional accuracy of the impeller forming through the ingenious design of the casting component 130. The configuration of the ventilation pipe 140 and the ejector motor 160 makes the production process more intelligent and efficient.
